Math Calculators

A cubic feet calculator finds the volume of a box-shaped space in cubic feet. Enter length, width, and height to get the volume, useful for shipping, soil, and storage estimates.

A ratio calculator simplifies, scales, and compares ratios. Enter two or more values to reduce a ratio to its simplest form or solve a missing term in a proportion.

A proportion calculator solves equations of the form a/b = c/d. Fill in three values and the tool finds the fourth using cross-multiplication, with the work shown.

A fraction calculator adds, subtracts, multiplies, divides, and simplifies fractions. Enter your expression and get an exact, reduced answer with each step explained.

A percentage increase calculator measures how much a value has grown relative to where it started. Enter the original and new values to get the percent change, with the formula shown.

A percentage difference calculator compares two values of similar status when neither is the original. Enter both to get a symmetric percent difference using their average as the base.

A factor calculator breaks a number or polynomial down into the pieces that multiply together to make it. Type your expression and get the full factorization with a clear, step-by-step explanation.

A slope calculator finds the steepness and direction of the line through two points. Enter the coordinates and get the slope, plus the related point-slope and slope-intercept forms.

An algebra calculator solves equations, simplifies expressions, factors polynomials, and expands products. Type your problem and get a full worked solution for every algebraic move.

A quadratic formula calculator solves any equation of the form ax² + bx + c = 0. Enter the three coefficients to get both roots, the discriminant, and a full worked solution.

A calculus solver works out derivatives, integrals, and limits with full working. Enter a function and the operation, and read a step-by-step solution rather than just the final value.

An integral calculator finds antiderivatives and definite integrals. Enter a function (and bounds if needed) to get the result with each integration rule applied step by step.

A derivative calculator differentiates functions and shows each rule. Enter an expression to get its derivative with the power, product, quotient, and chain rules applied step by step.

A statistics calculator summarizes a data set in one step — mean, median, mode, range, variance, and standard deviation. Paste your numbers and read off every measure of center and spread.

A standard deviation calculator measures how spread out a data set is around its mean. Enter your values to get the standard deviation, variance, and mean in one pass.

An average calculator finds the arithmetic mean of any list of numbers. Enter your values to get the mean along with the sum and count that produced it.

A long division calculator divides multi-digit numbers and lays out every step. Enter the dividend and divisor to see the quotient, remainder, and the full written working.

A Pythagorean theorem calculator solves right-triangle side lengths. Enter any two sides to find the third using a² + b² = c², with the working shown.

A simplify calculator reduces a math expression to its simplest form — combining like terms, canceling common factors, and applying arithmetic rules until nothing more can be reduced. Enter your expression and get the simplified result with each step explained.

A square root calculator finds the number that, multiplied by itself, equals your input. Enter a value to get its square root, including results like the square root of 2 or 144.

A cylinder volume calculator with two boxes: enter the radius r and height h to get the volume V = πr²h instantly, plus total and lateral surface area, worked examples, and the mistakes a cylinder volume calculator catches.

A law of cosines calculator with three boxes: enter sides a and b plus the included angle C to get the third side c and both remaining angles instantly - the Pythagorean theorem that works for any triangle.

A law of sines calculator with three boxes: enter a side and the two angles of your triangle to get both remaining sides and the third angle instantly - no right angle required.

A normal distribution calculator with three boxes: enter x, the mean μ and the standard deviation σ to get the z-score, the left-tail probability P(X < x) and P(X > x) instantly.

A standard error calculator with two boxes: enter the sample standard deviation s and sample size n to get the standard error of the mean SE = s/√n instantly, plus the 90% and 95% margins of error.

A z score calculator with steps: type your values. The AI works out the z score, what it means, and the percentile.

An antiderivative calculator with steps: type any function. The engine finds its antiderivative instantly, and the AI explains every rule it used.

A partial derivative calculator with one math box and one dropdown: enter f(x, y), pick x or y, and get the partial derivative instantly - every other variable held constant, every rule intact.
